The decomposition technique uses separate sets of galaxy and quasar eigenspectra to efficiently and reliably separate the AGN and host spectroscopic components. The technique accurately reproduces the host galaxy spectrum, its contributing fraction, and its classification. 2006AJ....131...84V https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/84 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to II/259 : The SDSS Photometric Catalog, Release 3 (Abazajian+ 2005) VII/243 : SDSS quasar catalog.
